Thermal Energy Thermal energy is the total kinetic energy of the particles in an object Objects with more thermal energy have faster moving particles Objects with less thermal energy have slower moving particles More total molecules also means more thermal energy VIDEO https://www.youtube.com/watch?v=gNM_9etcJT0

Thermal Energy vs. Heat Heat is the transfer of energy between objects that are at different temperatures. Absolute Zero is 0 Kelvin (0K), the temperature where no molecules will move!

Three Ways to Transfer Thermal Energy Conduction-transferring thermal energy from one substance to another through direct contact Ex. The handle of a metal spoon in a bowl of hot soup gets hot even though its not in the soup Convection-transfer of thermal energy by the movement of a liquid or gas Ex. Water boils in a pot on the stove Radiation-transfer of thermal energy through matter or space Ex. Light waves from the sun VIDEO https://www.youtube.com/watch?v=-7SRr-bnsKY

What happens when you rub your hands together very fast What happens when you rub your hands together very fast? How does thermal energy impact mechanical energy? What happens in EVERY energy transfer and makes it seem like energy is “lost”?

Which boy is experiencing more friction? Why???
